摘要:目前，随着我国经济的逐步增长，人们对居住条件生活环境的舒适性的要求越来越高，对中央空调的需求越来越大，对中央空调节能、舒适、健康更加关注。根据南京市的能源使用现状及目前的经济发展水平，从节能的角度出发进行设计，为人们提供一个舒适、安全、卫生的工作环境。

　　本设计是南京市某综合楼的空调工程设计，该建筑物共有六层。一层内吊顶下净高3.0米，二层房间房间内吊顶下净高3.0米，走廊内吊顶下净高为2.8米，三至五层走廊内吊顶下净高为2.6米，六层多功能厅内吊顶下净高为2.8米，吊顶的传热系数为0.9kcal/m2h℃。

　　根据合理利用能源的原则，因地制宜，在比较各种方案的可行性后，选择一个技术可靠，经济合理，管理方便的设计方案。最终确定方案为：大空间采用全空气一次回风的空调系统，小空间采用风机盘管加新风系统，本建筑物采用螺杆式冷水机组作为冷源。

　　设计内容包括: 空调负荷的计算；空调系统的划分与系统方案的确定；送风状态及送风量的确定；冷源的选择；空调末端处理设备的选型；风系统的设计与计算；室内送风方式与气流组织形式的设计及校核；水系统的设计及计算；风管系统与水管系统保温层和防腐设计；消声防振设计等内容。

Abstract:Now, with the gradual growth of our economy, people's living conditions in the comfort of the living environment have become increasingly demanding, and growing demand for central air conditioning, central air conditioning energy efficiency, comfort, health, more attention. According to Nanjing and the current status of energy use, economic development, from the perspective of energy-saving design, providing people with a comfortable, safe and healthy working environment。

　　　This design is the air conditioning in a complex building in Nanjing engineering design, the building a total of six. Under a layer of clear height of 3.0 meters within the ceiling, second floor room under the room ceiling clear height of 3.0 meters, under the corridor ceiling clear height of 2.8 meters, three to five corridors clear height of 2.6 meters under the ceiling, six multi-function Chamber under the clear height of 2.8 meters ceiling, ceiling heat transfer coefficient 0.9kcal/m2h ℃.

　　　According to the principle of rational use of energy, local conditions, the feasibility of various options in the comparison, select a technology, reliable, economical, easy management of the design. Finalize the program: a large space with full air conditioning system back to the wind, a small space by fan coil plus fresh air system, this building uses screw chiller for cooling.

　　　Design elements include: air conditioning load calculation; air conditioning systems and system solutions division to determine; air condition and determine the amount of air; cold source selection; air terminal handling equipment selection; air system design and calculation; room delivery Air way air distribution design and verification forms; water system design and calculations; air duct system and water system insulation and corrosion protection design; Noise vibration design content.
